Description

  The present invention relates to a binder binding tool that can easily bind a paper such as a loose leaf, and more particularly to a binder binding tool that can be easily opened and closed with one hand.

The following three types of binding tools for binding paper such as loose leaf are known.
In the first type, a plurality of ring rings formed in a semi-cut shape are provided opposite to each other on the substrate, and these opposed ring rings are opened and closed by operating operation pieces provided at both ends of the substrate. (Patent Document 1).
The second one includes a fixed substrate having a plurality of binding rings formed in a half-cut shape, and a movable substrate having a plurality of half-rings formed in a half-cut shape that engages with the binding rings of the fixed substrate. The fixed substrate and the movable substrate are pivotally attached at one end, and the movable substrate is opened in a fan shape with respect to the fixed substrate (Patent Document 2).
The third type includes a fixed substrate having a plurality of binding rings formed in a half-cut shape, and a movable substrate having a plurality of half-rings formed in a half-cut shape that engages with the binding rings of the fixed substrate, By operating a finger-hanging piece, the movable substrate is moved in a direction perpendicular to the longitudinal direction (Patent Document 3).

  In the first type, the opening angle of the binding ring cannot be increased so much that the paper cannot be inserted smoothly, and the operation is not performed when opening and closing the binding ring. The operation is troublesome because it needs to be performed with both hands.

  In the second type, since the fixed substrate and the movable substrate are pivotally attached at one end, when the binding ring is opened and closed, the opening on the pivoting side is poor and cannot be fully opened. It is difficult to insert or remove paper.

In the third type, since the movable substrate is moved in a direction orthogonal to the longitudinal direction, the movable substrate may come into contact with the cover of the file during the movement. When opening and closing the binding ring, it is necessary to hold the fixed substrate with the other hand so that the file does not move.
